- Refactor WorkflowVisualizer to use rank-based grid layout for better readability of parallel tasks.
- Improve edge rendering in visualizer with highlighting logic and curved lines.
- Update ReportPage tabs styling to be more distinct and card-like.
- Implement collapsible sidebar for Workflow Status visualizer with vertical text support.
- Add formatNodeName utility for cleaner task name display.
- Fix CSS issues in index.css.
- Add documentation for pending task: adding display_name to workflow DTOs.
- Fix `simple_test_analysis` template in E2E test setup to align with Orchestrator's data fetch logic.
- Implement and verify additional E2E scenarios:
- Scenario C: Partial Provider Failure (verified error propagation fix in Orchestrator).
- Scenario D: Invalid Symbol input.
- Scenario E: Analysis Module failure.
- Update `WorkflowStateMachine::handle_report_failed` to correctly scope error broadcasting to the specific task instead of failing effectively silently or broadly.
- Update testing strategy documentation to reflect completed Phase 4 testing.
- Skip Scenario B (Orchestrator Restart) as persistence is not yet implemented (decision made to defer persistence).
